PhD Studentship
Adaptive Parallel Optimising Compilation using Machine Learning
School of Informatics
Multi-core processors are the most viable means to delivering sustainable performance. However, this potential cannot be realised unless the application has been well parallelised. Unfortunately, efficient parallelisation of a sequential program is a challenging and error-prone task. It is generally agreed that manual code parallelisation by expert programmers results in the most streamlined parallel implementation, but at the same time this is the most costly and time-consuming approach. Parallelising compiler technology, on the other hand, has the potential to greatly reduce cost and time-to-market while ensuring formal correctness of the resulting parallel code. Given that the underlying processor architecture will change many times throughout the lifetime of the code, we would like parallel programs that are performance future proof too.
The project student will investigate new compiler directed approaches to delivering performance in a multi-core environment where the data input, concurrent workload and underlying architecture are evolving.
Probabilistic analysis can be used to determine program parallelism which can then be mapped to available resources. Central to this work will be the use of machine learning as a technique to learn and adapt the parallel code to this changing parallel landscape.
